Chanel Azure (657) is a very cool-toned, medium-dark teal with a metallic finish. It is a limited edition nail lacquer that retails for $28.00 and contains 0.4 oz.
Chanel Azure (657) Le Vernis Nail Colour ($27.00 for 0.40 fl. oz.) is described as a "metallic blue green." It's a brightened, bluish-teal with a metallic finish. It seems to shift a bit from blue to teal to green, depending on the angle and how the light hits the color. The color itself is interesting and complex. I'll be reviewing it soon, but Dior's Samba isn't an exact dupe for this--it is more of a true teal with less shift and more warmth. China Glaze Deviantly Daring is similar when Azure is in its blue stages, but it doesn't have the same green-teal shift. Zoya Charla has a very different finish (more glitter/sparkle) and is a darker, bluer polish overall.
